Any Evil Jumper stories out there?

I've read a bunch of Jumper stories where the Jumper tries to be a hero and a good person and thats all well and good, but are there any fics where the Jumper understandably goes a little mad with power? I'm surprised you don't see more of this, since it's highly likely that if you just give some random schmuck god-like power, they're gonna abuse it in some way, even if they try to rationalize it to themselves.
